[QUOTE="wvcountryboy, post: 454053, member: 28693"] I was wondering if anyone knew how far off the riflings nosler and sierra seat their bullets in their manuals. They tell the barrel, the length, the twist the velocity, and the most accurate powder tested but they dont tell one of the more important things. If they seat their bullets .050 off the lands and call it a max load and i seat mine .002 I will be over pressure. Also, I was wondering the severe difference in max load from nosler to sierra manual. For example: I shoot a 338 ultra mag. I realize the match king and partition are totally different bullets but max load was something like 4 grains difference with most powders. I dont have the manuals handy to check but thats just off the top of my head. In my rum, the nosler loads are ok, the sierra is about 2 grains hot. If I shoot the max load from sierra I will have loose primers in 2 shots and bad tattoos on the first. I am shooting 100-125 fps faster than their max velocity with 2 less grains but i am using a 30 inch barrel. Sorry for the jumping around but back to the seating depth, I made a dummy to have my reamer made for my ultra mag. I had what I thought would be a short throat so I could shoot small bullets. I use a 700 action with a davidson ramp but the other day i was curious to how much room I would have in the magazine of a magnum action..... it wont fit. I looked at the saami coal in the book and it is way shorter than mine.I am figuring my round wouldnt chamber in a factory cut chamber but does anyone know if they are possibly like a weatherby and have .250 free bore? That would explain why I cant shoot max loads. Thanks for your input in advance. Jeff [/QUOTE]
